Portable Wear Edge Milling Machine

Wear edge milling machine: portable machine for removal of wear edges in cylinder liners

Wear edge milling machine, VKS, is a pneumatically driven, portable machine designed to remove wear edges in cylinder liners. It is not only easily adjustable for different wear edge positions, but it is also highly accurate thanks to its wheel-mounted design. Therefore, this minimizes the risk of accidental damage of liners, a frequent occurrence with manual grinding methods. In addition, the removal of wear edges minimizes piston pulling time and saves piston rings and liners, increasing engine efficiency. Finally, with VKS the complete removal of a wear edge takes no more than 25 minutes and in most cases even less, depending on diameter.

  • Applicable for liners 280 – 980 mm diameter
  • Down to 250 mm diameter depending on engine type.
  • Perfect wear edge removal in 15 – 25 minutes depending on diameter
  • Shortens piston pulling time and saves piston rings and liners
  • Easily adjustable for different wear edge positions
  • Air driven
  • Workshop and onboard versions available

Available for several engine makers, such as: Bergen, Caterpillar, MAN DIESEL, Sulzer, Wärtsilä, etc.

Easy to use

The milling head is easily adjusted to the exact position of the wear edge. It therefore easy to operate.

Accurate

The design is wheel-mounted, with both vertical and horizontal guiding at liner top end. It therefore prevents accidental damage of liners, often occurring with manual grinding methods.

Robust compact design

Positioning device with dial gauge easily available for correct setting.

Upgrade kit

VKS and VKS-A are easily upgraded to VKS-P and VKS-AP. Once upgraded, they can also be used in restricted areas where hot work is not allowed.

NEW!

VKS-P – a wear edge milling machine especially designed for use in restricted areas where hot work is not allowed.

VKS-P is the latest addition to our air-driven range of wear edge milling machines. It has been specially designed for use in restricted areas where hot work is not allowed. It is equipped with a slowly rotating air motor and a specially designed milling cutter. Moreover, the machine is delivered with a type examination certificate from Det Norske Veritas.
